Thief doesn't start

[REsolved] my windows 7 installation was in some bit broken i dont know. strange enough this was the only game that did not work.

i try to Play THIEF 4. But it doesn't even make its way to the loader.
I have a dual Monitor setup
with gtx 780 ti
i7 3770k
16 GB Ram
and Win7 x64 Ultimate

i tried nv driver 337.50 334.89 335.23.

what can i do? Anyone else having such output? would be nice to hear something. I tried all steps i found on steam and in the Troubleshoots they offer at the eidos site.

Edit: i tried now even creating a new User account in Windows, didn't work. Validating didnt help, reinstalling didnt help, i tried to override the 64 bit executables with the 32 bit ones. what else?
i do not understand it, since deus Ex and Tombraider run flawless. I even downclocked my cpu to stock settings. i made a page file on my SSD (which i really wanted to avoid). Nothing i only get this output which is shown here. what the hell is wrong?
